No luck after trying to uninstall my programs.
As I've mentioned before I have tried limiting my framerate both through Nvidia Control Panel and through RTSS, as well as using Nvidia Control Panel's Vsync.
For now, I've found setting my Windows power profile to High Performance/Setting SpeedShift - EPP in Throttlestop to 0 seems to reduce the issue considerably, though I get some occassional stuttering in crowded areas.
